12V24 Plastic Injection Tools , Injection Molding Mold For PP / PVC
/ PE
About mold materials
The most important factors for choosing the suitable mold materials
are thermal strength and thermal stability.The main requirement is
to have good mechanical processing performance,
high hardness, less heat treatment deformation, good polishing
performance, and strong wear resistance and corrosion resistance.
The Commonly used injection mold steel include
P20,718,718H,NAK80,S316,M300.
And NAK80 now are widely used in plastic injection mould .As to
NAK80, it is Prehard die steel and hardness is about 37-43hrc with
good polishing performance.
Also we will respect the customer requirement for choosing the best
raw material acoordingly.
About the Cold runner and hot runner
Cold runner systems are used in injection molding machines to
convey material from the nozzles to the mold cavity. The material
cooled in the channel between the nozzle and
the cavity (the runner) and ejected with the part.
A hot runner system is an assembly of heated components used in
plastic injection molds that inject molten plastic into the
cavities of the mold.
About the craft process
processing methods used in plastic mold are lathe, boring machine,
milling machine, grinding machine, drilling machine, sawing
machine, CNC, EDM , wire cutting.
(1).Cap Mould : grinding→fly-cutter →CNC
Milling→drilling→lathe→boring lathe→electric pulse →fine
fly-cutter→polish→electroplate→install
(2).Preform Mould: grinding→drilling→lathe→boring lathe→fine
fly-cutter→electroplate→install
Surface finish process
polishing, sand blasting, heat treatment, painting, powder coating,
anodizing, electroplating, mirror polishing .
Life time and warrantty
With the strict quality control ,it can keep long life time that
reach more than 500000-1000000 shouts and up.We guarantee you one
year for repair.
